Ankara
–
Ankara, formerly known as Ancyra and Angora, is the capital of the Republic of Turkey. With a population of 4,587,558 in the center and 5,150,072 in its province. Ankara was Atatürks headquarters from 1920 and has been the capital of the Republic since its founding in 1923, the government is a prominent employer, but Ankara is also an important commercial and industrial city, located at the center of Turkeys road and railway networks. The city gave its name to the Angora wool shorn from Angora rabbits, the long-haired Angora goat, the area is also known for its pears, honey, and muscat grapes. Ankara is an old city with various Hittite, Phrygian, Hellenistic, Roman, Byzantine. The historical center of town is a hill rising 150 m over the left bank of the Ankara Çayı, a tributary of the Sakarya River. The hill remains crowned by the ruins of the old citadel, as with many ancient cities, Ankara has gone by several names over the ages. It has been identified with the Hittite cult center Ankuwaš, although remains a matter of debate. In classical antiquity and during the period, the city was known as Ánkyra in Greek and Ancyra in Latin. Following its annexation by the Seljuk Turks in 1073, the city known in many European languages as Angora. The form Angora is preserved in the names of breeds of different kinds of animals. The oldest settlements in and around the city center of Ankara belonged to the Hattic civilization which existed during the Bronze Age and was gradually absorbed c, 2000–1700 BC by the Indo-European Hittites. In Phrygian tradition, King Midas was venerated as the founder of Ancyra, but Pausanias mentions that the city was far older. Persian sovereignty lasted until the Persians defeat at the hands of Alexander the Great who conquered the city in 333 BC, Alexander came from Gordion to Ankara and stayed in the city for a short period. After his death at Babylon in 323 BC and the subsequent division of his empire among his generals, Ankara, by that time the city also took its name Ἄγκυρα which, in slightly modified form, provides the modern name of Ankara. Other centers were Pessinos, todays Balhisar, for the Trocmi tribe, the city was then known as Ancyra. The Celtic element was probably relatively small in numbers, an aristocracy which ruled over Phrygian-speaking peasants. However, the Celtic language continued to be spoken in Galatia for many centuries

Turkey
–
Turkey, officially the Republic of Turkey, is a transcontinental country in Eurasia, mainly in Anatolia in Western Asia, with a smaller portion on the Balkan peninsula in Southeast Europe. Turkey is a democratic, secular, unitary, parliamentary republic with a cultural heritage. The country is encircled by seas on three sides, the Aegean Sea is to the west, the Black Sea to the north, and the Mediterranean Sea to the south. The Bosphorus, the Sea of Marmara, and the Dardanelles, Ankara is the capital while Istanbul is the countrys largest city and main cultural and commercial centre. Approximately 70-80% of the countrys citizens identify themselves as ethnic Turks, other ethnic groups include legally recognised and unrecognised minorities. Kurds are the largest ethnic minority group, making up approximately 20% of the population, the area of Turkey has been inhabited since the Paleolithic by various ancient Anatolian civilisations, as well as Assyrians, Greeks, Thracians, Phrygians, Urartians and Armenians. After Alexander the Greats conquest, the area was Hellenized, a process continued under the Roman Empire. The Seljuk Sultanate of Rûm ruled Anatolia until the Mongol invasion in 1243, the empire reached the peak of its power in the 16th century, especially during the reign of Suleiman the Magnificent. During the war, the Ottoman government committed genocides against its Armenian, Assyrian, following the war, the conglomeration of territories and peoples that formerly comprised the Ottoman Empire was partitioned into several new states. Turkey is a member of the UN, an early member of NATO. Turkeys growing economy and diplomatic initiatives have led to its recognition as a regional power while her location has given it geopolitical, the name of Turkey is based on the ethnonym Türk. The first recorded use of the term Türk or Türük as an autonym is contained in the Old Turkic inscriptions of the Göktürks of Central Asia, the English name Turkey first appeared in the late 14th century and is derived from Medieval Latin Turchia. Similarly, the medieval Khazar Empire, a Turkic state on the shores of the Black. The medieval Arabs referred to the Mamluk Sultanate as al-Dawla al-Turkiyya, the Ottoman Empire was sometimes referred to as Turkey or the Turkish Empire among its European contemporaries. The Anatolian peninsula, comprising most of modern Turkey, is one of the oldest permanently settled regions in the world, various ancient Anatolian populations have lived in Anatolia, from at least the Neolithic period until the Hellenistic period. Many of these peoples spoke the Anatolian languages, a branch of the larger Indo-European language family, in fact, given the antiquity of the Indo-European Hittite and Luwian languages, some scholars have proposed Anatolia as the hypothetical centre from which the Indo-European languages radiated. The European part of Turkey, called Eastern Thrace, has also been inhabited since at least forty years ago. It is the largest and best-preserved Neolithic site found to date, the settlement of Troy started in the Neolithic Age and continued into the Iron Age

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Seating capacity
–
Seating capacity is the number of people who can be seated in a specific space, in terms of both the physical space available, and limitations set by law. Seating capacity can be used in the description of anything ranging from an automobile that seats two to a stadium that seats hundreds of thousands of people. The International Fire Code, portions of which have adopted by many jurisdictions, is directed more towards the use of a facility than the construction. It specifies, For areas having fixed seating without dividing arms and it also requires that every public venue submit a detailed site plan to the local fire code official, including details of the means of egress, seating capacity, arrangement of the seating. Once safety considerations have been satisfied, determinations of seating capacity turn on the size of the venue. For sports venues, the decision on maximum seating capacity is determined by several factors, chief among these are the primary sports program and the size of the market area. Seating capacity of venues also plays a role in what media they are able to provide, in contracting to permit performers to use a theatre or other performing space, the seating capacity of the performance facility must be disclosed. Seating capacity may influence the kind of contract to be used, the seating capacity must also be disclosed to the copyright owner in seeking a license for the copyrighted work to be performed in that venue. Venues that may be leased for private functions such as ballrooms and auditoriums generally advertise their seating capacity, seating capacity is also an important consideration in the construction and use of sports venues such as stadiums and arenas. The seating capacity for restaurants is reported as covers, a restaurant that can seat 99 is said to have 99 covers, seating capacity differs from total capacity, which describes the total number of people who can fit in a venue or in a vehicle either sitting or standing. Use of the term public capacity indicates that a venue is allowed to more people than it can actually seat. Again, the total number of people can refer to either the physical space available or limitations set by law

Turkish language
–
Outside of Turkey, significant smaller groups of speakers exist in Germany, Bulgaria, Macedonia, Northern Cyprus, Greece, the Caucasus, and other parts of Europe and Central Asia. Cyprus has requested that the European Union add Turkish as an official EU language, in 1928, as one of Atatürks Reforms in the early years of the Republic of Turkey, the Ottoman Turkish alphabet was replaced with a Latin alphabet. The distinctive characteristics of Turkish are vowel harmony and extensive agglutination, the basic word order of Turkish is subject–object–verb. Turkish has no classes or grammatical gender. Turkish has a strong T–V distinction and usage of honorifics, Turkish uses second-person pronouns that distinguish varying levels of politeness, social distance, age, courtesy or familiarity toward the addressee. The plural second-person pronoun and verb forms are used referring to a person out of respect. Turkic languages belong to the Altaic language group, the Turkic family comprises some 30 living languages spoken across Eastern Europe, Central Asia, and Siberia. Turkish is a member of the Oghuz group of languages, a subgroup of the Turkic language family, there is a high degree of mutual intelligibility between Turkish and the other Oghuz Turkic languages, including Azerbaijani, Turkmen, Qashqai, Gagauz, and Balkan Gagauz Turkish. The earliest known Old Turkic inscriptions are the three monumental Orkhon inscriptions found in modern Mongolia, erected in honour of the prince Kul Tigin and his brother Emperor Bilge Khagan, these date back to the second Turk Kaghanate. The Seljuqs of the Oghuz Turks, in particular, brought their language, following the adoption of Islam c. Turkish literature during the Ottoman period, particularly Divan poetry, was influenced by Persian, including the adoption of poetic meters. One of the tasks of the newly established association was to initiate a reform to replace loanwords of Arabic. By banning the usage of imported words in the press, the association succeeded in removing several hundred words from the language. While most of the words introduced to the language by the TDK were newly derived from Turkic roots, owing to this sudden change in the language, older and younger people in Turkey started to differ in their vocabularies. While the generations born before the 1940s tend to use the terms of Arabic or Persian origin. The past few decades have seen the work of the TDK to coin new Turkish words to express new concepts and technologies as they enter the language. Many of these new words, particularly information technology terms, have received widespread acceptance, however, the TDK is occasionally criticized for coining words which sound contrived and artificial. Some earlier changes—such as bölem to replace fırka, political party—also failed to meet with popular approval, some words restored from Old Turkic have taken on specialized meanings, for example betik is now used to mean script in computer science

Stadium
–
Pausanias noted that for about half a century the only event at the ancient Greek Olympic festival was the race that comprised one length of the stade at Olympia, where the word stadium originated. In modern times, a stadium is officially a stadium when at least 50% of the capacity is an actual building. If the majority of the capacity is formed by grasshills, the venue is not officially considered a stadium. Most of the stadiums with a capacity of at least 10,000 are used for football, or soccer. A large amount of sports venues are also used for concerts. Stadium is the Latin form of the Greek word stadion, a measure of length equalling the length of 600 human feet, as feet are of variable length the exact length of a stadion depends on the exact length adopted for 1 foot at a given place and time. Although in modern terms 1 stadion =600 ft, in a historical context it may actually signify a length up to 15% larger or smaller. The equivalent Roman measure, the stadium, had a similar length — about 185 m -, the English use of stadium comes from the tiered infrastructure surrounding a Roman track of such length. Most dictionaries provide for both stadiums and stadia as valid English plurals, although etymological purists sometimes apply stadia only to measures of length in excess of 1 stadium. The oldest known stadium is the one in Olympia, in the western Peloponnese, Greece, initially the Games consisted of a single event, a sprint along the length of the stadium. The stadion, a measure of length, may be related to the Stadium, Greek and Roman stadiums have been found in numerous ancient cities, perhaps the most famous being the Stadium of Domitian, in Rome. The excavated and refurbished ancient Panathenaic stadium hosted a version of the Olympic Games in 1870,1875,1896 and 1906. The excavation and refurbishment of the stadium was part of the legacy of the Greek national benefactor Evangelos Zappas, the first stadiums to be built in the modern era were basic facilities, designed for the single purpose of fitting as many spectators in as possible. One such early stadium was the Lansdowne Road Stadium, the brainchild of Henry Dunlop, banned from locating sporting events at Trinity College, Dunlop built the stadium in 1872. Some 300 cartloads of soil from a trench beneath the railway were used to raise the ground, other early stadiums from this period in the UK include the Stamford Bridge stadium and Anfield stadium. In the U. S. However, many of these caught fire. All of the 19th-century wooden parks were replaced, some only a few years. Goodison Park was the first purpose-built football stadium in the world, walton-based building firm Kelly brothers were instructed to erect two uncovered stands that could each accommodate 4,000 spectators
